WATCH: Jennifer Lopez Nearly Naked & Christina Aguilera Moves Like Jagger at the American Music Awards!

Jennifer Lopez’s outfit was barely there at last night’s American Music Awards! The Boricua superstar sparked huge buzz with her nude jumpsuit with sparkly accents–but hey, our girl looked good.

At Los Angeles’ Nokia Theatre, the 42-year-old ripped through a medley of her hits including Until It Beats No More, and “Papi”. As she performed, Lopez peeled off layers of her outfit until she finally wound up in the sheer bodysuit she rocked for "On the Floor" music video. During “On The Floor”, J.Lo was joined by Pitbull and backed it up like a Tonka truck all over the blue-eyed Miami-based rapper. We're not so sure how well that went over with Lopez’s estranged husband Marc Anthony, who also performed with Mr. 305 later on in the evening. At one point, J.Lo even hopped in a Fiat 500—talk about a dedicated spokeswoman!

But our fave Lopez moment came when she snagged the award for Favorite Artist in Latin Music. “It's been a really amazing year in so many ways,” Lopez said before she dedicated the award to all her "gente Latina."

“It's been up and down and just exciting and overwhelming,”  she told the audience of the last year.

Lopez’s performance wasn’t the only one that was memorable. Part-Ecuadorian songstress Christina Aguilera performed her hit song “Moves Like Jagger” with Adam Levine from Maroon 5. The 30-year-old singer, who wore her light blonde hair teased, donned a sparkling white dress. Puerto Rican crooner Bruno Mars also took home the award for Pop/Rock Male Artist.
